SPEED-ALARM FOR. LAU'IUVEHIGLES.

To all whom it may concern:

Be it known that I, PETER E. PAuLsoN, a citizen of the United States, residing at Eastedge, in the county of Baines and State of North Dakota, have invented certain new 7 and useful Improvements in Speed-Alarms for Autovehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appe'rtains to make and use the same.

This invention relates to speed alarmsfor auto vehicles, and the principal object of the invention is to provide simple and eflicient means for sounding a bell or giving an alarm when the speed limit is exceeded as indicated upon the speedometer.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in

'which Figure 1 is a front elevation of a speedometer provided with a speed alarm made in accordance with this invention,-

Fig. 2 is a vertical sectional view of the same, and

,The pointer 5 is connected to a squared portion 6 of the journal member 4, and the inner end of the member is rovided with a threaded ortion7 to receive a nut 8. The pointer 5 1s covered with an insulating sleeve 9 which terminates short of the point 10, said point forming a contact element. Extending at right angles to the pointer 5 is a contact lug 1-1. The pointer 5 1s desi ed to be set on the scale 2 to any desire speed limit. The speedometer operating hand 5" is covered with an insulating sleeve 11, said hand being ivoted'upon a pin 12, said pin being rotatetlbythe speedometer mechanism.

member 4, which is provided with a milled head 13, said conductor leading to a hell 5, and by conductor 0 to a battery d. A conductor a leads from the pin 12 ofthe hand 5* to the battery (Z.

From the foregoing it will beobvious that i when the pointer 5 is set to any desired speed on the scale 2, when the speed of the and shoul the speed of the car he on the increase, a further movement of the indicating hand 5 will also move the pointer 5 owin to the engagement of the indicating han with the contact lug. After the vehicle has been stopped or the speed reduced, the pointer 5 will remain'in the position to which it was moved by the indicating hand 5 and indicate the speed of the car in excess of the speed for which the pointer 5 was set to indicate. The pointer 5 may be readily reset through the medium of the head 13. Various changes may be made in the details of construction without departing from the spirit and scope of the-invention as defined in the claim.

' What is claimed is The combination with a speedometer ha'ving a dial, an indicating hand cooperating with the dial, and a glass panel, of a journal member in the panel provided with an operating head, a pointer secured at one end to the ournal member, a contact lug carried by the ointer for engagement by the indicating and, and a sleeve of insulation mounted on each hand.

In testimon whereof I aflix my signature in presence 0 two witnesses.
